ATTIC LOUVER Henry Avers and James W. Ground, Stillwater, Okla.

Application June 9, 1949, Serial No. 98,032

This invention comprises lnovel and usefulv irnprovements in atticlouvors and more speciiically pertains to a Ventilation ,louverconstruction for Walls and the like, and generally consists of a louver`construction formed of angle iron members rigidly secured together toform a frame tolgether with a series of slanting, parallel verticallyspaced `slats `carried by the frame together'with a screen securedthereto.

The principal object of this invention is to provide a ventilationlouver of a sturdy butJ simple and inexpensive construction which willAsatisfactorily admit the passage of air therethrough but will preventthe ingress of rain, snow, the direct rays of the sun and the like.

A further object of the invention is to provide an improved louverconstruction which is ideally adapted for use with vertical walls or thelike, and in Whichan improved screening is assembled as a part of thelouver construction.

`A further object of the invention is to provide a louver constructionas set forth in the foregoing objects which shall include a condensationand Water collecting trough for collecting Water impinging andcondensing on the slats of the louver, and discharging the sameexteriorly of the wall with which the louver is associated.

A still further object of the invention is to provide a louverconstruction which shall be formed of commercial angle iron structuralunits and which are assembled readily in an improved relation to lessenthe Weightand increase the strength of the construction.

These, together with various ancillary features and objects oftheinvention whichwill later .become apparent asthe following descriptionproceeds, are attained by this invention, a preferred embodiment ofwhich has been illustrated by way of example only in the accompanyingdrawings, wherein:

Figure l is an elevational View of a portion of the vertical wall of abarn or similar building with which the improved louver construction isassociated;

Figure `2 is a horizontal sectional View taken substantially upon theplane of the section line 2-,-2 thereof, parts being broken away andomitted;

Figure 3 is a vertical transverse sectional View taken substantiallyupon the plane of the Asection line 3--3 of Figure 1, parts being brokenaway and omitted; and,

Figure 4 is an assembly perspective View of the various elements makingup the improved louver construction.

5 ola-mls.v (o1. sas- 121) Referring now more Aspeeldcally to .the@06empanying drawings, wherein like numerals ,deS- ignate similar partsthroughout the Various views, there is disclosed the improvedlouverconstruction indicated generally by the numeral `I 0 `mounted inoanopening of a vertical wall kI2 Awhich may form a part of a :barn orhouse or the like, it being understood that .the louver is customarilyrecessed .in this opening flush with the exterior surface of the Wallerpartition l2.

The louver construction I U includes top and bottom rail mem-bers I4 andlr6, which are of angle iron construction 4as are also vertical endmembers IB ,and 2D together with vertical intermediate members 22 and24.

Considering first the intermediate members, it will be seen that thesemembers `,maycon-veniently be formed of .U1-.shaped .channel ,membersthe web portion of which alie nllOYided With a series ofcoextensivevertically spacedand inclined slots z s which marne isposed atanySuitable angle such as orthe We, Ato-their upper and lower ends, theintelm late channel members lareV provided with horizontally diSPQSedflanges land .310 for a purpose Whichuwll `loe lar setirorth.

The end members ,t8 and '20 are of l-fshered cross-,section andareprovidedwith similar'coextensive vertically `space :diificliried slots26, the endmembers at their upper and lower'extrernities likewiseterminating Tin hlizbntally `disposed flanges `32 and 3 4. Whileitheslots 2S of thintermedate members `2z and .2`4extnld entirely throughtheseme'mbers, the `correspending `slots of the end members `Ill ,andV2B may either be formed,as grooves `in theA surface of one wall of theaV gle iron `end members,4 or may comprise slots ertendiig therethrough,as desired;v

.A plurality lslatsl having their )Sides ver# tending upwardly aS at 38,and downwardly as at-4 respectively have thesesides disposed `in ,any.convenient angle ,such aS in vertical planes; these slats beinedsposd'throuehthe `Slots-fifi 0f the intermediate membersuand `extemlinginto or through the slots 2B of the end memberswhere.- .by the ,slatsare rmly mounted in overlapping relation to form vanes or shutters whichslope .downwardly and 'outwardly `of the 'louver @91'1- structon, `asShown nfFigures 1 and 3;

If desired, the ,slatsmay `be welded where they engage .any of' the end0r intermediate members in order Ito 'increase the rigidity of` theconstfllldudn. M y.

` The top and bottom rails I4 and I6 preferably comprise horizontalportions 42 and 44 which have respective vertically upstanding and de- 3pending flanges 46 and 48 respectively which are adapted to be disposedsubstantially flush with the vertical wall surface l2 as will be seenfrom Figures 1 and 3. At what may be termed the inner side or inner endof the shutters, the top and bottom rails areprovided with Verticalflanges 50 and 52 which extend inwardly of the shutter. It isintendedthat the portions 42 and 44 shall be seated upon each of the flanges 28and 32, and 30 and 34 respectively, and be Welded thereto to complete arigid rectangular frame-V work.

In order to render the rectangular framework of the shutter more rigid,a gusset plate 54 may be welded to the joint formed between each of theend members and a top or bottom rail, as will be readily apparent fromFigure 1,

It is proposed to further reinforce and strengthen the framework of thelouver construction by adding reinforcing members to the vertical endmembers, these reinforcing members being likewise of L-shapedconstruction and being indicated generally by the numerals 56 and 58.Each of these members Vincludes perpendicularly disposed vertical walls60 and 62, the walls 60 having perpendicular, outwardly extendingvertical flanges 64 which are adapted to abut against and be welded tothe laterally extending surface `of the end members I8 and 20 while thewalls 62 are adapted to abut against and be welded to perpendicular,inwardly extending vertical flanges 66 formed on the walls 68 of the endmembers,

as shown in Figure 2. It will thus be seen that vision of the watercollection trough disposed be- Y neath the bottom rail, and this troughmay conveniently comprise a horizontally disposed plate l2 having anupstanding back or inner flange 14 with integral upstanding end flanges76, and a depending outer or front flange 18. As shown best in Figure 3,the Vwater collection trough is mounted upon the inside of the wall inwhich the ventilated louver construction is disposed, with a Vverticalflange 'I4 disposed inwardly of the screening l0, with the plate 12underlying the bottom railv I6 and with the forward flange 'i8 beingwelded or otherwise secured ,to the rear surface of the depending flange48 of the bottom rail. Any suitable means may be provided for conductingmoisture collected in this collecting trough to the exterior surface ofthe wall with which the louver is constructed.

From the foregoing, the construction and operation of the device will bereadily understood and further explanation is believed to beunnecessary. However, since numerous modifications and changes willreadily occur to those skilled in the art after 'a consideration of theforegoing specication and accompanying drawings, it is not desired tolimit the invention to the exact 4 construction shown and described, butall suitable modifications and equivalents may be resorted to, fallingwithin the scope of the appended claims.

We claim:
